WAX-SHEETING MACHINE.

I Application filed September 23, 1919. Serial No. 325,642.

To all whom it may concern:

Be it known that-I, GARDNER H. Winona, of Medina, Ohio, have inventedilacertain new and useful Improvement in ax-Sheeting Machines, and dohereby declate that the following is a full, clear, and exactdescription thereof.

This invention relates to the manufacture, or production of wax in sheetform, with especial reference to sheets that are formed intocomb-foundation for use in bee hives, and the object, generally stated,is to improve machinery of the class in which melted wax istaken. up bya revolving cylinder and forced through a contracted passage, or betweendies, so that the proper temperature conditions may be mai'ntainedin thecylinder, with a minimum use of cooling water; the plafiicity of the waxpassing through the dies may be controlled and not be dependent on, orseriously affected by the prevailing temperature of the room in whichthe machine is worked; the width of the sheet delivered be subject tothe requirements of the case; the product finally delivered preventedfrom tearing; and the capacity of the machine increased.

The machine shown in the drawings is capable of achieving all thejust-mentioned results, and, therefore, is esteemed a most satisfactoryembodiment of the invention, but the invention is not dependent uponthat particular embodiment, but is any construction that is comprehendedwithin the scope of the appended claims.

In the drawings Fig. 1 is a view of such machine, partly in sideelevation, and partly in section;

Figs. 2, 3 and 4, are, respectively, end views and a longitudinalsection of the cylinder;

Fig. 5 is a detail view showing the sheettrimming knives.

In the drawings, 10 designates the pan containing the molten wax, 11 thecylinder revolving partially therein, and 12 the die opening throughwhich the wax is forced to emerge as a sheet of the desired thickness.

The cylinder 11 is hollow, being composed of a cylindrical shell. andheads 13 at the opposite ends thereof which are held .together by bolts14 that reach from head to head. The ends of the shell are bevel-led andare engaged by undercut grooves 15 in the inner faces of the heads, andexternal diameter of shell and head is the same, so that for its entirelength the cylinder 'is'of uniform diameter and is available forreceiving the Wax. The cylinder shaft 16 has an axial bore 17 reachingwithin each of the cylinder ends, one of which communicates with radialor diametrica-l holes 17 that lead. to the periphery of the shaft beyondone of the heads, and the other bore communicates with radial holes 17 bthat lead into the other head, and into the interior of pipes 19 thatextend parallel with the cylinder axis, and close to the inner peripheryof the cylinder, and reach nearly to the other head which is chambered,or provided with cavities or pasterior. By suitable inlet and outletpipe connections with the respective bores 17, it will be seen that acooling medium, suchas water, may be circulated through the cylinder,and through the heads so that through its length, from end to end, thecylinder may be cooled to the requisite temperature to solidify themelted wax on its periphery. The pipe perforations 21 being small,arereadily clogged and require to be cleaned, otherwise water inincreased pressure and volume must be used. The pipes are, therefore,made readily removable, for cleaning purposes. To that end each isinserted and removable through a hole '22 provided in the cylinder headto which it is attached, the hole being closed, and the pipe thereatbeing secured, by a screw plug 23 that engages a flange 240 on the pipeend.

The die opening 12 is formed b the adjacent faces of upper and.1owerdies 24, each in the form of a hollow block or box through which aheating medium, such as hot water, or steam, is passed and thus atemperature maintained for the die faces which results in the desiredplasticity of the wax in passing through the die opening. A pipe 2.5supplies steam or/ other heated medium to one end of one box, and anoutlet pipe 26 leads from the corresponding end of the other box, andthe two boxes are connected at the opposite end by a pipe 27.

It is desirable to trim the sheets of wax to a particular width, and tovary such width. supported from a cross bar 29 bolted to the For thispurpose, two knives 28, are

upper die block. so that the emerging sheet encounters them and issmoothly cut to the desired width. said knives being adjustable towards.and from each other on said rod.

From the dies. and after being cut or trimmed. the sheet enters a bodyof water 30 in a pan 31 through which it passes, and is caused to emergeby passing over a roller 32 supported at the far end of the pan 31, and,thence, passes to the winding arbor 33. The passage of the sheet throughthe water 30 renders it less likely to tear apart as it rolls upon thewinding arbor.

1. Apparatus of the kind described comprising a pan for melted wax, acylinder revolving in the latter, of uniform diameter throughout itslength. and dies receiving wax from the cylinder.

2. Apparatus of the kind described comprising a pan for melted Wax, acylinder revolving in the latter, of uniform diameter throughout itslength. and chambered throughout substantially its length to re ceive acooling medium, and dies receiving wax from the cylinder.

3. Apparatus of the kind described comprising a pan for melted wax. acylinder revolving in the latter, of uniform diameter throughout itslength, and composed of a shell and chambered heads in comunication witha source of supply of cooling medium, and dies receiving wax from thecylinder.

4:. Apparatus of the kind described comprising a pan for melted wax, ahollow cylinder revolving in the latter. and perforated pipes removablysecured within the cylinder.

5. Apparatus of the kind described, comprising a pan-for melted wax. ahollow cylinder having closed ends. revolving in the latter. a shaft onwhich the cylinder is mounted. extending through the ends thereof,perforated pipes in the cylinder removably supported therein in thespace outside the shaft. and means establishing communication betweensuch pipes and a source of supply of cooling liquid outside thecylinder.

6. Apparatus of the kind described comprising a pan for melted wax, anda hollow cylinder revolving in such pan, comprising a shell of uniformexternal 1 diameter throughout its length, and chambered heads closingthe shell ends of the same diameter as the shell exterior, anddistributing pipes to establish communication between the chambers inthe heads and the outside of the cylinder to circulate a cooling mediumthrough the cylinder.

7. Apparatus of the kind described comprising a pan for melted wax. ahollow cylinder revolving in the latter, perforated pipes within thecylinder adapted to be passed through holes in the cylinder head, andremovable means to close said holes and secure the pipes to the head.

t3. Apparatus of the kind described coniprlsing a pan for melted Wax,dies through which the wax is passed, and means for controlling thetemperature of the wax passing throu h the dies.

9. Apparatus of the kind described comprising a pan for melted wax, diesthrough which the Wax is passed consisting of hollow blocks, and meansfor circulating a heating medium through said blocks.

10. Apparatus of the kind described comprising dies. means for forcingwax through the dies. and means for cutting the wax longitudinally afterpassing through the dies. said means comprising knives supportedcontiguous to the exit side of the dies and directl therefrom.

11. pparatus of the kind described comprising dies. means for forcingwax through the dies, and means for cutting the wax longitudinally afterpassing through the dies, and consisting of knives adjustable towardsand from one another and mounted directly on the exit side of the dies.

12. Apparatus of the kind described comprising dies, means for forcingwax through the dies, a Water-holding means receiving the wax sheetsemerging from the dies directly from the dies. and a roller receivingthe wax sheet directly from the water.

In testimony that I claim the foregoing I have hereunto set my hand.
